Compact, Portable Dryer for Moisture Testing
The NEW FBD 2000 is a compact, portable dryer. Its powerful air delivery system makes drying a very fast operation. The fluidization mixes and separates the particles, minimizing the risk of abrasion and the creation of lumps, and resulting in a truly representative sample. The comprehensive set of controls makes it ideal for use in the laboratory on a wide selection of materials.
Drying times range from a few seconds to minutes.
Higher rates of heat transfer ensure faster and more homogeneous drying than oven, microwave, or vacuum drying.
Suitable for most granular and powder materials.
Precise controls ensure uniform and reproducible results.
EASY TO USE
Manageable controls with straightforward settings.
Air is heated by a 2kW electric heater and can be set to any temperature up to 200ºC. The temperature is controlled by a closed loop system that can achieve stability to within 1ºC.
A built-in digital timer enables the drying time to be pre-set and the drying operation to be carried out unattended. At the end of the cycle time an alarm sounds and the unit switches off automatically.
The air flow rate and fluidization velocity are infinitely variable from 0.4 to 2.4m³/min volume (0.9 to 5 m/sec speed). Optimum levels can be set by observing the sample behavior within the glass tubs.
FILTER BAG MATERIAL
Filter bags are usually nylon or terylene with other materials available to suit more aggressive conditions such as sustained high temperature drying.
A power fan delivers the high volume air flow from the base unit into a special tub assembly which holds the sample material.
The flow of heated air passes through a diffuser gauze which supports the bed and evenly distributes the air as it passes into the tub.
A filter bag at the top of the tub keeps the sample in while allowing the air, moisture and gases to escape.
Single tubs come in 2 and 5 liter sizes in either stainless steel or glass (see below). A multi-tub is also available for drying four samples at one time. Glass tubs are particularly useful for observing the fluidization process to establish optimum settings.
An attachment is also available for the efficient drying of test sieves (see right).
